Okay thread got confusing so let me break down a few things here, sorry for the length but trying to consolidate this discussion to what your asking OP.

.... When i play games like BF4 i get only 45FPS on ultra using 970, but idk why sometimes it goes up to 120fps when i exit the game or restart my PC.
Yes that is possible to be 'that low' because BF4 is a very high demanding game, if something is amiss (the PAGEFILE below). Here is what independent numbers say

The reason "goes up to 120fps when i exit the game or restart my PC" is your exiting the part that needs to 'demand' so much from your system. As you exit the game it doesn't need to 'render' all the extra information anymore (where that guy is siting behind the bring wall and the Jeep next to him driving at you), sot his is normal.

I have been using MSI afterburner to monitor whats happening.
Dawis67_AE :
IOnly one way to find out. Install MSI afterburner and run it while gaming. Then about after 5 mins of gaming go out of the game and look at MSI afterburner. On the HW monitoring you right click and click pause. Then u see how much GPU power u use. Most of GPUs should use 90% of power.
Your not using MSI afterburner correctly. You don't 'exit' to look at it, you enable and use the OSD (On Screen Display) so you see IN GAME what your 'performance is'. You do this as follows (helps to read the instructions btw on all this techie stuff)
Two items are in your system tray, the Airplane (MSI Afterburner) and the Blue 'computer card' (RivaTuner Statistics Server - aka RTSS). Right click on each and select SHOW.
In MSI click on settings. Click on Monitoring tab then select the items to monitor one at a time. When you select something LOOK DOWN BELOW, above HARDWARE MONITORING HISTORY LOGGING PROPERTIES is SHOW IN ON-SCREEN DISPLAY checkbox. To see 'in game' that stat, you CHECK the CHECK box to SHOW it On the Screen Display. Click OK. Click the MINIMIZE not the X to close MSI.
in RTSS make sure the START WITH WINDOWS and SHOW ON-SCREEN DISPLAY are ON. You can modify how large small they display with the ZOOM slider, and then tweak where it will show on your screen. As I play 1080p, I normally have it right of the center of the screen, so I use 1000 x 75 in the numbers UNDER the 'monitor' screen you see on thsi panel. Once done click the DOWN ARROW - NOT the X in the top right .
Now as you play a game it will display the stats so you can see when things are happening in game and how it affects your 'stats'.

... my RAMs Pagefile usage is overloaded. It uses 9000 out of 8000MB roughly and now as i exited game and have only Chrome,Skype, Steam and Origin running my Pagefile usage is at 5400MB and Ram usage at 3600MB. And when games do run with good FPS and when GPU isnt bottlenecked my Pagefile usage under gaming is below those 8000MB. Any ideas?
Okay some BASIC COMPUTING 101, so please forgive me as you don't seem to understand the basics here.
1) if you open Task Manager and select SHOW ALL PROCESS FROM ALL USERS at the bottom check box you will see there is MUCH more then " only Chrome,Skype, Steam and Origin running". So please get that notion out of your head, there is RAM (memory) used to make the mouse seen on the screen, each letter, the icons on your desktop, more RAM used if you store FILES on your desktop then short cuts to them, all the apps in your tray, etc. all eat up RAM (the memory you physically put in).
2) PAGEFILE is Windows 'trick' to stop NOT ENOUGH RAM - BSOD that happened before XP. Windows 'borrows' storage space on the HDD, to 'swap' in and out from when it doesn't have enough RAM. If you started BF4 and had only 2GB of RAM available, but BF4 wants 8GB, then it uses the 1GB of RAM, and keep 'swapping' in and out the other 8GB as it needed it for the game. This is additional time, HDDs are much slower than RAM, all the swapping also impacts LOADING the game code as needed, etc.
3) Software works like this: Software (BF4) is stored on a Drive (HDD), all the code. The player says I want to run that game (code) so the computer pulls a certain amount of the code at time, by copying it from HDD to the RAM, in 'chunks'. As it pulls it, the RAM passes it to the CPU to process or.. to do something with it. Does it need to play a sound? Is it sending your CHAT IM over the Internet? Is it needing to render that Helicopter? The CPU passes that 'chunk' to that device and that device is responsible to do 'its job' (sound card makes sound, GPU renders on the screen, etc.). This is constantly happening till enough 'code' is in the RAM that it doesn't need to ask for it again till you 'do something ' (hence when you exit the game the game just has the exit menu for example, nothing 'else' is going on). So if it is busy doing this for the normal code, but then runs into "oops not enough RAM, quick Batman to the Swap FILE!" So now in addition to all this 'normal work' now you add on these extra swapping of HDD / RAM / CPU on top of it, so it slows down all the works.
No that would be AFTER you knew the information on what VOLTS your running, making sure your running the right SPEED you needed for your CPU. So in this case as we can see your running a i7 at 4GHz, the CPU tab of that page shows you should be running a Core i7 Haswell Refresh i7-4790K. This can be confirmed by clicking CPU on left side of SPECCY and will show you the NAME of your process. This is important because a i7-4790K is enabling OverClocking, which means to get the higher speeds out of the RAM you would want to pick the correct RAM, so they made it easier by providing a chart that shows you the guaranteed compatible RAM, and what clock speed it will be initially at before you OC it.
As you pointed out YOUR Crucial Memory is NOT on here, only these other models
Crucial BLS4G3D1609DS1S00.16FMD DDR3 1600 N/A 1.5V DS 4GB 4
Crucial BLS8G3D169DS3.16FED DDR3 1600 N/A 1.5V DS 8GB 4
Crucial CT102464BA160B.C16FED DDR3 1600 N/A 1.5V DS 8GB 4
As they are NOT the same exact one (note they have specific Volts and such on them) this might explain why it isn't "kicking in" Dual Channeling and may not be 'exactly' compatible as you needed it to be. IMHO I would replace the RAM out with the LISTED on UNLESS you get a GUARANTEE from Crucials Website / in writing from the person your buying it from that it is the SAME thing as these LIMITED models. Personally I would ONLY stick to this list on this website.
Dawis67_AE :
So what do i do? Any suggestions?
Well first dont' bump the thread. Second as I pointed out on my system, if your going to multitask with things, then you need more RAM. As YOU also said " i cant find a crucial memory stick with the same serial as on my curent memory stick" means you probably also do not have the correct type of RAM that is perfectly timed / volted / etc. to this Mobo and the CPU you have installed. I would suggest then to not only INCREASE the RAM you have (2 x 8GB sticks? 4x4GB sticks?) but get all the SAME correct type as per this website
http://www.msi.com/support/mb/Z97-GAMING-5.html#support-mem that THEY say will work properly IN that Mobo, otherwise your ON YOUR OWN because they won't support things that they do not 'know' if it works or not and won't spend the time nor money just to find out for YOU, unless you wish to PAY them to do so, then that is a different story.
Hopefully this lengthy but accurate reply will make it a bit easier for you to understand and make a better conscious decision.
